'useful Improvements in Oil-Gauge Valves,

of which the following is a specification.

This invention relates to an oil gauge valve and more particularly to atype of valve having a body portion, a conduit in said portion and aslidably mounted closure stem which directly closes the conduit by thesliding action of the stem and it is the object of this invention toprovide a crank case, within which an oil level must be maintained at'orabove a predetermined point, with a valve operated from the side of thevehicle carrying the crank case so that whenthe valve is actuated oilwill flow out indicating that the oil is at least to its proper level.

As is well known with a certain type of automobile, to determine the oillevel within the crank case it is necessary to reach under the car andopen a petcock through which oil will flow after it is at or above'theproper level, and my type of valve eliminates the necessity for gettingbeneath the automobile.

Other objects and advantages will be seen and the invention readilyunderstood from the description of the accompanying drawings in which: I

Fig. 1 is a fragmentary transverse section through an automobile takenbehind the crank case.

Fig. 2 is a plan view shown in section with the closure stem allowingcommunication through the conduit shown in dotted line.

Fig. 3is a section on line 33 of Fig. 2.

My valve is shown attached to the rear vertical side of the crank case lsupported within the vehicle 2 and having the valve 3 positioned at apoint on the crank case at which the oil level within the same must beat least maintained. The valve comprises same is closed. Slidably.mounted in the bore 6 is the closure stem 7 projecting beyond at one endand having an enlarged portion 8 formed thereon. so as to form ashoulder 9 adapted to abut the end of the body portion and limit themovement of the stem. The other end of the stem projects beyond the bodyportion in the opposite direction upon which is mounted a coiled spring10 abuttlng the end of the body portion at one end and a cotter'pin 11at the other end, this spring normally kee ing the valve closed.

Extending throug the nipple 5 is a conduit 12 which terminates in thebore 6 and is then taken up again in'a second conduit 12' which isdiametrically opposed to the conduit 12 and which has communication withthe same when an annular groove 13 formed in the stem is pulled back inalinement with the conduits as shown in dotted lines of Fig. 2. It isthus seen that the oil will flow from the crank case through the conduit12 around groove 13 and out conduit 12' and will be visible to theperson actuating the valve so that he will know that there is suflicientoil in the crank case.

The means for actuating the valve support comprises a rod 14 assing atone end through an aperture 15 1n the head 8 and slidably supported in abracket 16 depending preferably from the running board 17 andterminating in a handle portion 18 which may be readily'grasped so as toopen the valve and allow oil to flow out of the same.

Various changes in the details of construction of my invention may bemade by those skilled in the art without departing from the spirit ofthe invention as set forth in the appended claims.

What is claimed is:

1. A valve comprising a body having a duct formed therein, a stemmounted for sliding movement in the body and transversely of the duct,said stem being formed at a point intermediate its ends with an annularchannel, a head formed on one end of the stem, said stem being capableof occupying one extreme position in which the channel is inregistration with the duct, and another extreme position in which;thehead engages the body and the channel is disposed substantiallyexteriorly of thekbody to allow of the cleaning thereof, and esiligentmeans on the stem and engaging-the body" for normally urging the stem tothe second extreme position.

nection with the transmission ease'of an engine for determining thelevel of oil in the .,case, a body having a bore and a duct inter matingthe bore, a nipple. formed on the I body adapted for engagement with thetransmission case and interiorly communieating with said duct, a closurestem mounted for longitudinal sliding movement in the bore and providedintermediate ends with an annular groove adapted to register with theduct'for allowing the dew of 011 from the nipple through the bodyportion,

I V I v ahead formed on one end of the stem for 2. In a valvestructureifor use 111' conne limiting the sliding movement of the stem1n one dlrection, and a spring associated with the other endof the stemand engaging.

the-body for normally nrgingthe stem to a position in which the grooveis out of egistration with the duct and partly'pr ojeeted from the b yand, he head is in contact vwith the body. r

In testimonywhereof have signed my name to this specification.v
